Determination of melting point
Instrument:
Micro melting point apparatus WRS-2A, Melting point tubes
Determination of step:
Open switch, stable 20min.
First set the starting temperature than the melting point of the low 10 , heating rate 2 / min.
The sample was grind as fine as possible and load in a clean, dry melting point pipe ,until the sample was compressed into about 1cm high .When the actual temperature reaches the set temperature and stabilized . Inserted into the capillary with the sample, the simultaneous determination of three.
The determination of PH
Weigh a certain amount of samples into test tube, add a certain amount of water, shake and dissolve, determination of the pH used have been calibrated pH meter.
The determination of solubility
Weigh a certain amount of samples into test tube, add a certain amount of water, shake and dissolve, observe the solution.
The determination of UV absorbance
A certain amount of the sample was weighed to the nearest 0.0001g, into 10ml volume
